Can consumers save the planet by just buying green?

A doctoral dissertation states that awareness-raising for consumers and eco-labels for products are important, but they are not enough. Government- and market-promoted green consumerism operates as a peripheral activity that is only a safeguard against the most visible, damaging and immediate environmental and social problems.

Assessing the strengths of solar thermal desalination

Researchers propose an elegant theoretical framework to help others in the field better understand how various technological innovations can enhance solar thermal desalination (STD) performance. The framework is summed up in a straightforward equation that can be universally applied to all STD systems, including those that have not yet been developed.

A new method to automatically estimate rooftop solar potential

The progress of rooftop solar installations is often slowed by a shortage of trained professionals who must use expensive tools to conduct labor-intensive structure assessments one by one. Now, researchers are proposing a new, data-driven approach that uses machine learning techniques and widely available satellite images to identify roofs that have the most potential to produce cost-effective solar power.

What counts for our climate: Carbon budgets untangled

Different analyzes have come up with different estimates of how much CO2 humankind can still emit if we want to hold global warming to the internationally agreed 1.5 and well below 2 degrees Celsius limits, but a lack of clarity of the reasons causing these variations has created unnecessary confusion, a new study shows.
